End user centricity

End user centricity is key at SUMSUM. It is our mission to co-create products that really matter and reduce the delivery gap.


Quality with capital Q. We take the time to elicit your needs and translate them to epics, features and user stories.

Our values

This is how we drive success and growth


We value ownership, where we strive to be impactful, lead with purpose, and proactively drive positive change in everything we do.


We believe in the power of collaboration and consciously creating an environment where we embrace failures as learning opportunities.

Shared prosperity

We foster a flat organization, where we believe in sharing, caring, and embracing change for collective growth. There's no "I" in team.
